V-BALL VALVES PROVIDE PRECISION STEAM CONTROL
Bonomi North America has introduced 2-piece stainless steel V-ball valve packages said to provide precision steam control. The company’s low-torque units are factory-assembled with its Valbia electric or pneumatic actuators. The CSA-approved NSF 372/61 certified direct-mount 2-piece V-ball packages have a smaller footprint fit where others can’t, the company says, reducing installation materials and labour costs. Users can choose 30/600, 600 or 900 V-ball units with company’s one-part-number system.

SEAL AREA SHAFT GUARDS PROTECT PUMP OPERATIONS
ProSpec Technologies has introduced the GlandGuard seal area shaft guard. The innovative design mounts on the mechanical seal gland rather than the pump housing to guard against physical contact with the rotating exposed shaft as well as offering a significant degree of splash protection, the company says. The shaft guards are said to be quick to install and easily field modified to suit a variety of pump and seal designs. Units install on the mechanical seal gland and allows full access to gland flush, drain, vent and quench connections for single, double, cartridge and non-cartridge seal designs. Depending on the gland bolt circle and the shaft diameter, either the inside mounted or the outside mounted design is used. Breakaway tabs and adjustable slotted mounts allow for easy field fitting to accommodate various pump and seal configurations.
Carlon Meter has upgraded and expanded its JLP Plastic Meter product line to 3 sizes, higher flow rates, and pressure rating. The JLP meter is available in three thread sizes, 1/2, 3/4, and 1 in., and operates at flow rates from ¼ to 50 gpm and pressure up to 100 psi. The nylon-housed meters are suitable for aggressive water such as reverse osmosis or de-ionized water. Optional pulse outputs for signaling controllers or remote readers are also available. Temperature range is 35° to 105°F with an accuracy of ±2% when operating between minimum and maximum flow range.
The NS series floating ball valves and NS series butterfly valves from A-T Controls are certified to meet the requirements of NSF 61 (Drinking Water System ComponentsHealth Affects) and NSF 372 (Drinking Water System Components- Lead Content). This means that NS Series valves are certified for use (by Underwriters Laboratory) in water treatment, water purification, potable water, and water distribution systems and conforms with North American lead content requirements for “lead-free” plumbing. These valves hold CRNs (Canadian Registration Numbers). NS butterfly valves are available in sizes 2 to 24 in. and have Class 150 wafer or lug flanges. NS ball valves are available with threaded, socket weld, butt weld, Class 150, and Class 300 end connections. Applications for the series also include reverse osmosis and desalination.
